->''And now, on with the opera. Let joy be unconfined. Let there be dancing in the streets, drinking in the saloons, and necking in the parlor. [[TheJackBennyShow Play, Don.]]''
-->-- '''Otis B. Driftwood'''

''A Night At the Opera'' was a 1935 MarxBrothers film, the first made in their switch from Paramount to MGM. Promised a free rein but [[ExecutiveMeddling forced by producer Irving Thalberg]] to focus the chaos against [[ComedicSociopathy the bad guys who deserve the mistreatment]], ''Opera'' became the largest box-office hit of the Marx Brothers' filmography. There's a fine debate over this or ''DuckSoup'' as the Marx Brothers' best film as well as one of the funniest movies ever. It was subsequently {{Homage}}d by the Zucker Brothers' movie ''Film/BrainDonors''.

Not to be confused with the Music/{{Queen}} album, ''Music/ANightAtTheOpera (1975)'' which was named after the movie. (Or with the Music/BlindGuardian album, which was named after the Queen album.)

----
!!This film is associated with the following tropes (if you dare!):

* AllPartOfTheShow: Gottlieb tries to invoke this by on going in costume when he and Henderson pursue Tomasso and Fiorello (also hiding in costume) onto the stage, but the hijinks that ensue flatten any hopes of this trope working.
* AtTheOperaTonight
* BrickJoke: At the end when Gottlieb is blackmailed into accepting Rosa, Riccardo, and Driftwood back as opera employees, Driftwod and Fiorello repeat the rip-the-contract routine from the beginning.
* TheCastShowOff: The scene on the boat where Chico plays the piano? That's not dubbed in. He was actually that good. (In the vaudeville days, he used to play the piano ''blindfolded.)''
** Kitty Carlisle had previously sung opera onstage for real, and Allan Jones, while not classically trained, was a genuinely talented singing star of the day. And of course, Harpo playing the harp.
* ChekhovsSkill: Tommaso (Harpo)'s rope-climbing and acrobatic skill.
* CorruptCorporateExecutive: Driftwood (Groucho), manager of Mrs. Claypool. He overhears that Lasparri is going to earn $1000 per night so he soon scrambles to intercept the deal...he is keeping a small profit from that $1000 dollars and paying to the singer... $10, [[CrossesTheLineTwice minus a 10% to him for negotiating the deal]].
-->'''Driftwood:''' I figure as long as he doesn't sing too often, he can break even.
* CrowdSong: Whenever Riccardo sings.
* DeadpanSnarker: Take a guess...
* DepartmentOfRedundancyDepartment: Contract clauses:
-->"The party of the first part shall be known in this contract as the party of the first part."
-->"The party of the second part shall be know in this contract as the party of the second part."
* TheDogBitesBack: Shortly after being whipped by Lasparri, Tomasso takes the opportunity to knock him out (twice!) with a blow to the head.
* EmergencyImpersonation: Harpo, Chico and Jones gag three famous airmen and impersonate them. They are later required to give a speech. Bizarre quotes and hilarity ensues --[[TheSpeechless Harpo plays a mute]]-- and their PaperThinDisguise doesn't last for long.
* EntitledToHaveYou: Lasparri towards Rosa. He helps arrange her debut in America just so he can have her, even though she's clearly uninterested, and largely to satisfy his own ego. When he sees her with Riccardo he has her kicked out of the show.
* {{Expy}}: All three Marxes, plus Margaret Dumont, play basically the same characters they play in every other movie.
* ExtremeOmnivore: Tomasso, who eats a lit cigar and a tie for starters.
* {{Gaslighting}}: When the team finally reaches america, they move beds from one room to the other to anger the detective and drive him batty.
* FoodPorn: The scene where Chico, Harpo and Ricardo finally get to eat will make any viewer seriously hungry for Italian food. Pasta with sauce, salamis, whole tomatoes, wedges of cheese, loaves of bread, and bottles of wine - all served on a single plate!
* GettingCrapPastTheRadar:
-->'''Driftwood: ''' You're willing to pay him a thousand dollars a night just for singing? Why, you can get a phonograph record of 'Minnie the Moocher' for 75 cents." (Pause) For a buck and a quarter, you can get Minnie.
* GettingTheBoot: The elevator man punts Driftwood down the stairs after Driftwood's firing.
* GoldDigger: Driftwood lusts after Mrs. Claypool's money, and he isn't exactly subtle or great at hiding it.
* GrandeDame: Mrs. Claypool, a social-climbing opera lover.
* HarpoDoesSomethingFunny: As usual, a few examples of this, such as the breakfast sketch in Groucho's apartment.
* TheHeckler: Driftwood heckles the opera shamelessly while Tomasso and Fiorello are disrupting it in the pit and on stage. ''Boogie boogie boogie!''
* {{Homage}}: The 1992 film ''BrainDonors'' is a lovingly-crafted tribute.
* IllTakeTwoBeersToo: If not the TropeNamer, than at least the UrExample.
* {{Jerkass}}: The full-of-it Lassparri.
* JerkWithAHeartOfGold: Driftwood is rude, abusive, screwy, cheap, thieving, and a ManipulativeBastard, but he sees to it the good guys prevail and that the lovers Riccardo and Rosa get their big break.
* LighterAndSofter: Those who object to the MGM films, even ANightAtTheOpera, will claim it's because the Marxes were made to be ''nicer'' (see JerkWithAHeartOfGold).
* LiteralMetaphor
-->'''Driftwood: '''You see that spaghetti? Now, behind that spaghetti is none other than Herman Gottlieb, director of the New York Opera Company. Do you follow me?
-->'''Mrs. Claypool: '''Yes.
-->'''Driftwood: ''' Well stop following me or I'll have you arrested!
* LogicalFallacies: Half of the hilarity comes from Groucho's elaborate wordplay and mind games.
-->'''Driftwood''': That woman? Do you know why I sat with her? Because she reminded me of you.
-->'''Mrs. Claypool''': Really?
-->'''Driftwood''': Of course, that's why I'm sitting here with you. Because you remind me of you. Your eyes, your throat, your lips! Everything about you reminds me of you. Except you. How do you account for that? ''(beat)'' If she figures that one out, she's good.
* {{Malaproper}}
-->'''Driftwood: ''' It's all right, that's in every contract. That's what they call a sanity clause.
-->'''Fiorello: ''' You can't fool me! There ain't no [[SantaClaus Sanity Claus]]!
* MuggedForDisguise: After Tomasso bonks Gottleib on the head ''again'', Driftwood takes his tux to get into the opera.
* NiceToTheWaiter: Lasparri establishes his position as the resident {{Jerkass}} by abusing Tomasso--though he's GenreSavvy enough to feign kindness in Rosa's presence.
* OnlyInItForTheMoney: Lasparri refuses to sing for the crowd on the docks because he's not getting paid for it.
* OnlySaneMan: Subverted. They simply didn't have the budget for one. Everyone - even the straight-laced lovers and the evil {{Jerkass}} - gets sucked into the Marx Brothers' madness.
* OvercomplicatedMenuOrder: Groucho, playing the shady social consultant Otis B. Driftwood and operating solely along the lines of the {{Rule of Funny}}, orders two to three portions of what seems to be everything on the menu in an illogical way, punctuating his selections after each item with an order for "three hard-boiled eggs" for the stowaways hiding in his stateroom.
* OverlyLongGag: "And two hard-boiled eggs!" ". . . and two hard-boiled eggs."
** *HONK*
*** "Make that three hard-boiled eggs."
*** HONK HONK HONK HONK HONK HONK HONK HOCK [[OverlyLongGag HONK HONK HONK HONK]]
*** "Either it's foggy out or make that another twelve hard boiled eggs"
* ProducePelting: Lasparri gets an apple thrown at him when he tries to sing an encore after Riccardo and Rosa's lauded performance.
* RefugeInAudacity: From the very first lines -
--> (For context, Driftwood is sitting with his back to Mrs Claypool, the woman he was supposed to have dinner with, having had dinner with another woman and the waiter has just given him the bill)
--> '''Driftwood:''' Nine dollars and forty-eight cents...?! This is an outrage! ''(throws the bill to the woman)'' If I were you, I wouldn't pay it! ''(walks away)''
* TheRemake: ''BrainDonors'', an all-but-the-name retelling of ''Opera''.
** All but the name and the opera, that is.
* ShoutOut: While Driftwood tries to hide the three stowaways in his room while the cop looks around:
-->'''Henderson''': What's this!?
-->'''Driftwood''': Why that's the fire escape. And that's a table, and this is a room, and there's the door and I wish you'd use it. I... [[GrandHotel I vant to be alone.]]
* TheShowMustGoOn: The confused and increasingly frustrated Lassparri keeps singing, even when the scenes behind and in front of him change rapidly.
* SpiritualSuccessor: the following MarxBrothers film ''Film/ADayAtTheRaces'', shares a similar plot but with different characters and scenery (a rest home in need of rescue and a horse race to be won).
* TheStateroomSketch: The TropeNamer
* [[StraightMan Straight Woman]]: Margaret Dumont as Mrs. Claypool, as always the prim foil to Groucho's antics.
* TapOnTheHead: Gottlieb, many many times, and once to the cop.
* TemptingFate: After getting fired, kicked down the stairs, and forced off a park bench by his troublesome colleagues, Otis thinks the worst is over.
-->'''Driftwood:''' Well, there's one consolation; nothing more can happen to me.\\
'''Passing Cop:''' Hey, get off the grass.\\
'''Otis:''' I was wrong. [tries to get a drink of water from the fountain, which promptly dries up.] People drink too much water anyway.
* ThisMeansWar: Used by Driftwood after the three fake airmen are confronted and leave. A ShoutOut to ''DuckSoup''
* ToughRoom: Driftwood gives an opening speech at the opera that in real life would have brought the house down, but the only response he gets is stony silence.
* YouGetWhatYouPayFor: Drifwood overhears that Lasparri is going to be paid one thousand dollars per night and decides to skim the deal somehow. He is clueless and assumes Fiorelos is Lasparri's manager, so he is willing to ''pay'' 10 dollars per night. He learns later that he was hiring Ricardo Baroni instead. It turns out Ricardo Baroni is an excellent singer, just unknown by the public.
